Correlation Between Coronary and Carotid Atherosclerotic Disease and Links With Clinical Outcomes

Vascular Disease Clinical Trial

Official title: Global Observational Study to Evaluate the Correlation Between Coronary and Carotid Atherosclerotic Disease (CAD) and Links With Clinical Outcomes

Status Completed

Clinical Trial Summary

The relationship of the natural history of atherosclerosis between different vascular beds has not been well characterized. Determination and comparison of the relative rates of progression and extents of atherosclerosis in the coronary and carotid arterial trees may have major impacts on clinical research and clinical practice. Correlation between findings in the carotid and coronary circulations is an important scientific and clinical topic to address. Results from a well design study incorporating imaging technologies that currently represent the gold standards for the assessment of coronary and carotid artery plaque burden, will have potentially impact on clinical research and clinical practice.

Clinical Trial Description

The CAIN-003 study was a prospective observational multi-center imaging study of subjects scheduled for clinically-indicated coronary angiography. CAIN-003 provided for the collection of baseline coronary angiography and IVUS imaging data along with baseline carotid ultrasound imaging. CAIN-003 study participants underwent follow-up coronary and carotid imaging at 2-years, and were then contacted by phone on an annual basis for an additional 3 years for the collection of cardiovascular and cerebrovascular clinical endpoints.

MHICC-31052012 was a prospective, observational, multi-center study of subjects who had successfully undergone baseline imaging in the dal-PLAQUE 2 study (A multicenter, double-blind, randomized, placebo-controlled study, evaluating the effect of treatment with dalcetrapib 600 mg on atherosclerosis disease). The dal-PLAQUE 2 study, which provided for the collection of baseline and 2-year follow-up coronary angiography, coronary IVUS and carotid ultrasound imaging data, was terminated by the sponsor prior to completion due to the discontinuation of the dalcetrapib drug development program. The MHICC-31052012 study allowed for the collection of follow-up imaging and clinical endpoint data from subjects who had successfully undergone baseline IVUS imaging in dal-PLAQUE 2.

Data from CAIN-003 and MHICC-31052012 was pooled to support the objective of determining the correlation and clinical relevance of these imaging endpoints.

The objectives of the CAIN-003 and MHICC-31052012 study were:

• To compare the extent of atherosclerosis present in the coronary vasculature with the extent of atherosclerosis present in the carotid vasculature at a single point in time.

• To compare the associations of atherosclerosis burden with coronary risk factors in the coronary arteries and carotid arteries, in multivariable regression.

• To compare the rate of atherosclerosis progression or regression in the coronary vasculature with the rate of atherosclerosis progression or regression in the carotid vasculature over a 2-year period.

• To determine the correlation between imaging biomarkers and cardiovascular outcomes over a 5-year period. ;
